Hello all, I have a basic question on wiring up my limit switches.

The leadshine MX3660 has 4 inputs which are suitable for limit switches, but that tells me that i can basically only have 4 limit switches total? ie X-, X+, Y-, Y+. So how do I set up limit switches for Z- and Z+?

Clive did mention on my my other thread that he just uses 1 limit switch per axis (ie X-, Y- and Z-) and uses them to home the machine, then rely on the soft limits to prevent crashing at the other end. Im happy to do that if I have to, but i would have thought a limit switch at each end would always be the safer option?

Thanks.
